53: Website Design & Aesthetics

Every graphic you use will slow down your site for its visitors.

According to some estimates, 20 percent of your visitors leave for every 10 seconds you ask them to wait for a page to download. That means, if 100 people arrive at your slow-loading page: 80 remain after 10 seconds; 64 remain after 20 seconds; 51 remain after 30 seconds; 41 remain after 40 seconds; 33 remain after 50 seconds; and after one minute you have lost all but 26 of the original 100 visitors. Rest assured all those who left will never return.
